Hello! I have a problem with the * plot_ci* fonction.

When I increase the value of the "n", the confidence intervals moves away from the true value of the population. and when I decrease the value of the "n", the confidence intervals move closer to the true value of the population.

The first graph corresponds to a value of n=1

The second graph corresponds to a value of n=100

The third graph corresponds to a value of n=150

The last graph corresponds to a value of n=1000
